` Be it knownthat I, WM. MGK. THORN- 'roN,"of Pottsville, in `the county of Schuyl- Mlill, inthe State of Pennsylvania,lhave' in-`` j vented a new and Improved Mode of Greas- V ing Leather; and I do hereby declare that the following isa full and `exact description thereof, reference being had to the accomi so " to describe its construction and operation.

i the adjustable screw. C the bottom. D, D,

`panying drawing, and to theletters of reference marked j thereon, like `letters referring tolike parts of the machine.

Figure `1, is s an*` end elevation. Fig. 2,` is a .r side view.

To enable others skilled in the art to make, and use my invention, I will proceed In Fig. 1, A, is the revolving lever. B,

the adjustable sides ofthe frameor curved levers, for elevating or lowering the maj chine. E, E, boxes through which the shaft passes. F, the shaftwith projection or rib Gr, let` into it `and extending entirely across it (between the boxes) 1, 2, 3, t, 5, 6', 7, are collars of different sizes from of an inch to one inch, and may be made of any required size, `accommodating the machine to the`width of the strap to be creased, they having* on their inner surface a groove which `ts `on to the projection or, rib, Gr, for the purpose of making them` revolve with the shaft F. the upper shaft. I, I, i j the sliding metallic rollers or creasers with adjustable screws a,f"a, for fastening `them at any positionrequired. On the inside of the creasersiorlrollers LI, I, are shoulders with grooves bf b, for compressing and creasingthe leather on its edges. J, J, the cogwheels for `driving the shafts F and H `with `the rollers or collars, and creasers or condensers.` K, K, washers on the inside of cogwheels. `L, the crank. M, the handle.

N, `N, adjustablefscrewsfor fastening the 1shafts in theirproper positions. O, O, the

` washers.

` Fig. 2, is a side elevation. A, the revolving roller let through the lower end ofthe curved lever orside `frame. in which it revolves.` A hook instead cfa hole may be used, and when it isnotin use the lever and screw may be takenout, and let the bottom `rest on the bench.

o is the head or end of the screw B. 1D, D, are the side arms or curved levers "through which the shaft I-I passes. "E,'\E`, boxes `through which the shaft F passes. Z oZ-Z Z `are projections at tliefends the piecesforming the boxes E,

13,` andinto which the ends of levers D, D,

are `fitted forming an oscillat-ing joint, J, J, the cogwheels thrown'out of gear. I, I the creasersor rollers. d, one of the adjustable set screws for fasteningit, in its required position, and keeping it firm making `it revolve on the shaft. L the crank.

The operationof my machine is as follows:` the end is fastened to a bench or stand .by screws or their equivalents, then `the collarsl l, 2, 3, 4, 5, 6, 7,/are adjusted singly, or two three or more of them according to the width of the strap to be creased are brought together (by this arrangement a strap can be creased from an eighth of an inch wide to any desired width).

In adjusting thecollars on shaft F to get the required width the metallic creasers are raised by means of the side arms or curved levers D, D, by which means they are raised above the collars and allow them to slide freely onthe shaft F. Then when the collars are adjusted to the size required the metallic creasers are adjusted to the size of the collars and fastened in their proper places by turning' the set screws a, a, the machine is then put in gear by turning the revolving Y lever A, so as to bring the screw B in a vertical position `bearing against bottom C thus allowing the flanges of the rollers or creasers to fall below the periphery of the collars until the shoulders with grooves Y), I), are'brought to bear on the collar or collars; the strap to be creased is then placedV on j the collar or collars thus arranged, and by turning the crank by the handle M the shafts revolve, and the strap is carried through between the rollers and collars, and is perfectly creased. The flanges of the creasers act as `guides to the strap in passing through the machine.

In the construction of my machine I do not use boxes of an ordinary kind as I dispense with caps screwed on the top of my shafts or creases. By means of the screws N, N, I undo the fastening of the shafts by taking the screws out and removing the washers o, 0, and unscrewing the set screws c, a I draw my shaft through the boxes E, E, and D D and take them out, or put them in at pleasure. -The adjustability-of my machine,l by throwing it out of` l gear for the purpofse of sliding the collars,

and rollers, is represented by the red lines as seen Fig. 2 (see red lines) here the levers D, D, are raised, and the machine shaft H, having flanges extending below the 0 thrown out of gear. periphery of the collars, and shoulders With Having thus fully described the construcgrooves b, b, operating in the manner, and

tion and operation of my machine, What I for the purposes, herein set forth.

5 claim as my invention and desire to secure by Letters Patent s WM. McK. THORNTON.

I claim the movable collars 1, 2, 3, &c., of Attest:

dierent sizes on shaft F in combination JNO. M. CARR,
